 Posted: Thu Jul 12, 2007 4:19 am Post subject: " C compiler cannot create executables" |
 |
|
I've just installed Gentoo for the first time on a PPC machine. A dual g4 powermac, to be specific. I had to use the manual installation method outlined in http://www.gentoo.org/doc/en/handbook/handbook-ppc.xml?full=1 and everything seemed to go well. When I had booted to the liveCD, and chrooted into my new environment, I was able to emerge left and right with no trouble.
However, once I booted off of the hard drive for the first time, I've found myself unable to emerge anything. emerge fails with the following: (in this example, I was emerging vim)
| Code: | checking whether make sets $(MAKE)... yes
checking for powerpc-unknown-linux-gnu-gcc... powerpc-unknown-linux-gnu-gcc
checking for C compiler default output file name...
configure: error: C compiler cannot create executables
See `config.log' for more details.

I think that it may have something to do with the flags set in my make.conf file, the contents of which I will also post here:
| Code: | # These settings were set by the catalyst build script that automatically
# built this stage.
# Please consult /etc/make.conf.example for a more detailed example.
CFLAGS="-O2 -mcpu=G4 -mtune=G4 -maltivec -mabi=altivec -fno-strict-aliasing -pipe"
CXXFLAGS="${CFLAGS}"
# This should not be changed unless you know exactly what you are doing. You
# should probably be using a different stage, instead.
CHOST="powerpc-unknown-linux-gnu"
GENTOO_MIRRORS="http://gentoo.osuosl.org/ "
USER="altivec -x -gtk -gnome -kde apache2 dvd dvdread server"

Any help would be appreciated. I was a linux user all through college, but drifted away back around 2001. I'm working my way back into using linux, and am amazed at how far things have progressed. But there are always those small things that stop you dead in your tracks. Small things like being unable to install any software.  |

I actually couldn't find where config.log was located. It wasn't in the current directory, and it wasn't in /var/log
Fortunately, I resolved the problem, and I now feel like an idiot. I'll say how I fixed it, in case anyone else is as foolish as me and encounters the same problem.
While I was emerging a number of packages, I wanted to also look at my kernel and play around a bit with the options in "make menuconfig" for building a better kernel later. Not knowing much about the internals of make, I didn't realize that this would be a problem, but I later deduced that my compilation problems started when I did that. Essentially, I had multiple instances of make trying to do work at the same time.
In short: rebooting resolved the problem, though I suspect that "make clean" would have done so also. |

I noticed in your make.conf this line:
USER="altivec -x -gtk -gnome -kde apache2 dvd dvdread server"
Should be USE="altivec -x -gtk -gnome -kde apache2 dvd dvdread server"
Not sure if that is related. Also you may want to check this page http://gentoo-wiki.com/Safe_Cflags and try the CFLAGS recommended there.

Oh wow! I really should have noticed that. Thanks. The devil is in the details. |
